ELECTRICAL CHARACTERISTICS (continued)
(+V
S
= +3.0V to +5.5V, unless otherwise noted. Temperature accuracy specifications apply for +V
S
= 3.3V for versions with -3 in
the suffix and for +V
S
= 5V for versions with -5 in the suffix. T
A
= -55癈 to +125癈, unless otherwise noted. Typical values are at
+V
S
= +5V, T
A
= +25癈.) (Notes 4, 5)
Note 4: All parts operate properly over the 3V to 5.5V supply voltage range. The devices are tested and specified for rated
accuracy at their nominal supply voltage.
Note 5: All parameters are measured at T
A
= +25癈. Values over the temperature range are guaranteed by design.
Note 6: There is no industry-wide standard for temperature accuracy specifications. Maxims standard is six-sigma. The three-
sigma specification is included to allow easier comparison to products built by manufacturers who use different standards.
Note 7: This specification indicates how often temperature data is updated. The devices can be read at any time without regard to
conversion state, while yielding the last conversion result.
Note 8: For best accuracy, minimize output loading. Higher sink currents can affect sensor accuracy due to internal heating.
Note 9: OS delay is user programmable up to 6 over-limit conversions before OS is set to minimize false tripping in noisy environ-
ments.
Note 10: Guaranteed by design.
Note 11: Default values set at power-up.
Note 12: All timing specifications are guaranteed by design.
Note 13: Unless otherwise noted, these specifications apply for +V
S
= +5VDC for LM75BIM-5 and LM75BIMM-5 and +V
S
=
+3.3VDC for LM75BIM-3 and LM75BIMM-3. C
L
(load capacitance) on output lines = 80pF, unless otherwise specified.
The switching characteristics of the LM75 fully meet or exceed the published specifications of the I
2
C bus. These parame-
ters are the timing relationships between SCL and SDA signals related to the LM75. They are not I
2
C bus specifications.
Note 14: Holding the SDA line low for a time greater than t
TIMEOUT
causes the device to reset SDA to the IDLE state of the
serial bus communication (SDA set high).
